DDROVED SOLE FCR. BOOTS.'-

' The Schedule referred to in these Letters Patent and making part ofthe sama.

To all whom it 'ma/y concern Be it known that we, CHARLES P. JoHNsoN, ofJamaica Plain, in the county of Norfolk, and State of Massachusetts, andFREEMAN K. SIBLEY, of Auburndale, in the county of Middlesex, and sameState, have invented a new and useful Improvement on Inner Soles forBoots and Shoes of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawing, formingpart of this specification, and in which- Fignrel represents an invertedplan or under-face view of an inner sole for boots and shoes inaccordance with our invention, and

Figure 2, a longitudinal section of the same. Similar letters ofreference indicate corresponding parts.

- Our invention consists in an inner sole for boots and shoes, eitherfixed or detachable, made of knitted hair- .clot-h, and stiifened with astrip of sheet-metal, sewed to it with wire of a different metal, such sole possessing numerous advantages over other inner soles, ashereinafter set forth.

Referring to the accompanying drawing- A represents an inner` sole, madeof knitted haircloth, and which may either be inserted or attached as apermanent sole within the boot or shoe, or be of a detachable character,'and slipped into the latter as re` quired or desirable. It will sulcehere, however, to refer to it as a detachable sole.

y, By making such inner sole of hair-cloth, formed by knitting, a strongand compact, but open-work sole is produced, which possesses thefollowing peculiarities,

-or advantages, viz: I

It admits of every provision for ventilation, and is lnot liable tobecome matted, or felted, or saturated with perspiration,

having its cellular character preserved till worn out, and so, while itretains its venti- V)ating-properties, having its 'warmth-retainingproperties preserved by the retention of air in its interstices betweenits yarns and fibres. Such a sole, too, in the use of it, producesiction, or acts as a slight irritant to promote circulation in the foot,and is-ofso elastic a character as to greatly ease the fatigue inwalking. It likewise is very durable.

To prevent the buckling of the sole, in putting on or pulling o theboot, when the sole is made detachable, that is, so that it cau be putin or taken out of the boot or shoe at pleasure, we run, down the centreof it, on its one side, or face, a stiffener, B, formed of a narrowstrip of zinc, sewed or stitched to the sole by copper wire a, so that'the same not only serves as a sti'ener, but also as a galvanic battery,whereby the health of the lwearer is promoted;

This is in no way analogous to a metallic sole, as the strip B onlyoccupies a very small portion of the width ofthe sole, while thestitching of it to the inner sole by copper wire answers n ot only tosecure it to said sole, but at the same time to give to the sole itsgalvanic character.

Ve are aware that galvanic soles, have heretofore been made. claim thisfeature per se; but

What is here claimed, and desired to be secured by Letters Patent, is-

An inner s ole, composed of horsehair, and stiened bya strip of metal,sewed on with wire, as shown and described, as a new article ofmanufacture.
